  • The BPF 2/6-… is a 6-helical resonator band-pass filter with aperture coupling between the resonators.
  • This filter can be used as a preselector to protect a receiver from interference from transmitters outside the band-pass limits.
  • When installed in the output of a transmitter, the BPF 2/6 reduces spurious signals.
  • The BPF 2/6-… is adjustable over the range 144 – 175 MHz.
  • Very compact due to use of helical resonators.
  • Careful choice of materials ensures reliable performance over a wide temperature range.
  • Extruded aluminium sections, steel racks and coaxial cables and connectors with teflon insulation ensure good mechanical strength.
  • The filter is black vinyl coated to prevent corrosion.
